S. A. THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. The Williamson Line of Warm Air Furnaces IF there is anything in the way of warm air systems for the heating, ventilating and sanita- tion of buildings of all kind5 that interests you, this catalog comes with a fixed value greater than that of the ordinary catalog of houses manufacturing and installing such apparatus. It is only one of several different catalogs we publish, de- scribing various types of heating and ventilating apparatus made and sold by us. We have been engaged in the manu- facture of heating and ventilating equipment for more than thirty years. Through years of increasing success we have added valued ex- perience to growing asset s — experience that has enabled us to put upon the market furnaces of unequaled merit. The Williamson line of warm air furnaces, to which this catalog is de- voted, has been designed to meet every possible condition. Here will be found illustrated and described furnaces for different classes of build- ings, for different grades of fuel, and in sizes to meet every requirement. During the many years of our business experience our constant aim has been to make The Williamson Line the best possible to produce. That our efforts have been successful is proved by the fact that from a small beginning we have attained the position of the largest manufacturers of warm air heating and ventilating equipment in the United States. This enviable position has been reached solely through the superior merit of our product. Our constant aims have been to improve the quality of our furnaces in material, workmanship and design, and to furnish a better made article — one that will give better and more economical heating results and greater satisfaction than any other firm can furnish at the same or even higher cost. First-class work can only be turned out by first-class workmen, tools, materials and facilities. The talent we employ in all departments is the very best. Our Foundry is thoroughly equipped for manufacturing 2 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. economically and well. Our castings are made of the best grade of gray iron castings, capable of withstanding successfully the strain of hard firing. It is possible for us to use a formula which produces furnace castings always uniform in quality, because our efforts are devoted exclusively to the manufacture of furnace castings, which results other concerns who make castings for commercial purposes as well, can not obtain. All castings are made on molding machines. Another feature of our organization to which we desire to call special attention is our Engineering Department, composed of skilled en- gineers, who are qualified to make plans and lay out work from archi- tect's drawings or sketches. The services of our Engineering Depart- ment are at the disposal of the trade at all times when desired for preparing heating plans for buildings of any character. We also prepare, if requested, a detailed estimate on the furnace and fittings necessary to install the work in accordance with plans thus made. This service many dealers find of material assistance in preparing bids, in further interesting customers and securing their contracts. Our plans are an excellent aid in erecting the work properly by furnace men of limited experience. We make no charge for preparing heating plans and estimates. The 300 Series Williamson Pipe Furnace has been developed as an answer to a constant demand for a furnace which combines all the good of the various furnaces made by the Williamson Heater Company during the past third of a century. It represents, therefor, the highest development of the pipe furnace, and its claim to superiority is fully borne out by exhaustive tests under every conceivable condition. We unhesitatingly claim for 300 Series the highest efficiency ever attained in a heater of this type, due to its unusual large radiating capacity and the amply and scientifically proportioned casing. THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. The Home ^ of the Williamson Line ON A FIELD of 26 acres in one of Cincinnati's most beautiful suburbs stands the Home of Williamson products. In that factory and by the men who here build, the name "Williamson" has become synonymous for quality, workmanship, and excellence of design. 4 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. ^f F 111 Nor has such a position been reached through any spectacular growth or attempt to attract attention, but rather through years of conscientious and consistent labor to make Williamson products just a little better; to adapt all the proved, worthwhile ideas to their product, so that it will always embody all that is good in furnace construction, and to secure uniformity and standardization of manu- facturing methods by the use of molding machines throughout the factory, as well as many other work-saving devices. This is the largest factory in the country devoted exclusively to the manufacture of heating equipment. It is a well-known truism that it is not practicable to combine, in one factory, the making of furnaces and stoves. The methods and formulae differ. Furnace manufacture is now, and always will be, a highly specialized field. The mass of steel and brick and concrete called the Williamson plant is an expression of the enterprise and industry of the man who, during the past 30 years or more, has here built the furnaces that bear his name. And the world, always ready to acclaim merit, has beaten a path to The Home of the Williamson Line. 5 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. THE 300 SERIES PIPE FURNACE Flat Tri- Diain.

S. A. Williamson Flat Grate, May be shaken or dumped while standing and without opening ash-pit door. This grate is operated by a neat wooden handle which is always cool and clean. Williamson Triangular Grate. Easy to clean and shake. Very durable. Dustproof Grate The famous Williamson dust- proof dumping and shaking device has been embodied in this furnace, which means that it may be shaken and dumped when standing upright and without soiling the hands or clothes. It is also unnecessary to open the draft door during these operations, and no dust is therefore allowed to enter the cellar and work its way up into the rooms. The front is made in two pieces, extending to the top of the casing, and is so arranged as to be gas tight. Large Feed Door Firing is made easy because of the large feed door, and a recess is provided in the feed pouch for a water coil, so that hot running water may be ob- tained without interfering in any way with the operation of the furnace. Full Width Ash-Pit Door The ash-pit door extends the full width of the ash-pit, so that ashes may be removed from every part without diffi- culty. Only new iron is used in the manufacture of the 300 Series Furnace. Each purchase of raw material is carefully an- alyzed by an experienced chemist before being accepted, and the mixture is kept uni- form at all times. In other 10 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. words, we are doing all that brains and science can do to manufacture a perfect, eco- nomical and durable furnace. Smoke Collar Extends Through Casing The smoke collar is of sufficient length so that it extends through the casing, and the smoke pipe is attached from the outside. This feature will be appreciated by those who have attempted to attach a new smoke pipe to one of the old-fashioned radiators with short collar requiring con- nection from the inside of the casing. Extra Large Casing Another feature is the extra large casing, which is from 4 to 6 inches larger than most furnaces of similar sized fire- pot. The casings are lined with asbestos paper and corru- gated bright tin, there being an air space of about 1 inch between the corrugations. The bright tin reflects the heat and the air space and asbestos in- sulator prevent the outside from becoming overheated. The furnaces with even num- bers are those supplied with the flat grate, which, as ex- plained before, enables the housewife to shake or dump it without stooping or soiling her hands. Another advantage of this type grate is that only the clinkers and ashes on the outer Radiator is of great depth and capac- ity, and of a type with a highly satisfactory record. This Fire-pot is of the well-known two- piece corrugated type. Very efficient and durable. Large Feed Door Opening with Recess for Water Coil. 11 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. Water Pan of ample size, insuring proper moisture for health and comfort. edges fall into the ash-pit, while the good fuel in the center is not disturbed. In the case of the ordinary draw-center grate, the good fuel is dumped while the clinkers around the edges are untouched. Grates Interchangeable Those with odd numbers are equipped with the triangular bar grate, which is of exceptionally strong construction and a very satisfactory grate. A big feature is the fact that the two grates are interchangeable, so that the furnace may be used with either, and the change from one type to another may be effected within a few minutes' time and without dismantling. Gas Ring In states where gas is used for fuel, this 300 Series may be equipped as a combination gas and coal furnace by substituting a gas ring for the upper fire-pot section. This gas ring is supplied with pipe and mixer ready to attach to the gas supply. Large Capacity Radiators The radiator is of the horseshoe type, the upper and lower sections being fitted together with tongue and groove joints, which are cast against a chill. This insures a uniform casting, and, as the groove ■ is filled with asbestos cement before the two sections are bolted to- gether, a permanent gas and dustproof joint is insured. Another feature of importance is that the floor of the radiator slopes outward, which greatly reduces the resistance to the products of combustion as they escape from the dome section. Two-Piece Fire-Pot The 300 Series is equipped with a two-piece fire-pot that has proved through several years to be durable and satisfactory. The corruga- tions give it a large radiating surface, and the depth is such that it will keep fire for a long time. Large Opening into Radiator An important factor for efficiency is a large opening between the dome section and the radiator. In the 300 Series with a 24-inch fire-pot this opening is 12 inches, and it is centered directly over the fire-pot. Gas Ring. 12 THE WILLIAMSON HEATER CO., CINCINNATI, U. S. A. OUR No. 240 FOR LARGE HOMES, SCHOOLS, CHURCHES, HALLS, ETC. This furnace is practically the same as the 300 Series, having similar ash-pit, fire-pot and feed sections, the only difference being in the radiator, which is of the middle joint type. We supply this furnace with the 30-inch fire-pot only, and it is particularly designed for very large residences, schools, churches, halls, stores, etc., in fact, any place where an extra powerful heater is required. The flat grate is of the same dustproof type as the 300 Series, and either flat or triangular grate may be specified. Flat Grate Series Tri- angular Grate Series 240 245 Diam. Casing Inches 58 Diam.

OUR No. 75 SOMETIMES a furnace is de- veloped that, through sheer merit, keeps its place in the front rank of the leaders in spite of improvements and the develop- ment of other types. This is true of the Williamson No. 75 Furnace, which, on account of its extremely heavy construction and proved durability, is termed a heavy duty furnace. This type and size is especially adapted for use in schools, churches, stores and public build- ings where a heating system receives a great deal of abuse. Shipping weight, complete with casing, is approximately 2,885 pounds. Heating capacity for public buildings is from 60,000 to 80,000 cubic feet. The capacity for residence heating is from 1, 130 to 1,400 square inches of piping. Dimensions Diameter of Casing ^ l A" Height of Casing 77 " Height of Casting 66 " Diameter of Firepot 29}/£" Diameter of Firepot Bottom 28M" Depth of Firepot 12 " Diameter of Grate 17 " The Grate is composed of two sections, a center round section which is operated by means of a yoke or wishbone-shaped cast- ing, and an outer ring section, operated by means of a clutch that engages and disengages by moving back and forth on the arm of the yoke. Special attention is called to the bell top directly under the radiator which alone weighs from 950 to 1,000 pounds. This bell top has an enormous radiating surface, greatly increasing the efficiency of this heater. Ordinarily the products of com- bustion are carried into the radia- tor through a single opening, but in the case of the No. 75 Furnace, these are let into the Radiator through five tubes, thus securing perfect combustion and increasing the capacity of the Furnace. The Radiator is made of sheet steel with cast top and bottom heads. This method insures a quick response and efficient heat- n g with small fire. The No. 75 Furnace has been on the market in its present form for more than twenty years, and many dealers claim that it is thebest furnace ever made by the company. We have never received a com- plaint on the construction or heating capacity of this type. We therefore believe that we are justified in taking it for granted that it has met the most exacting demands imposed upon it, and we recommend it for the purposes to which it is adapted with this long record of satisfactory service and durability in mind. 15 THE WILLIAMSON HEATER CO., CINCINNATI, U.
